The Relation Between Heavy Alcohol Use and Bar Patronage: A Latent Growth Model Journal of Studies on Alcohol 57,4 (July 1996): 410-418. Also: http://www.jsad.com/jsad/article/The_Relation_between_Heavy_Alcohol_Use_and_Bar_Patronage_A_Latent_Growth_M/339.html Cohort(s): NLSY79 Publisher: Center of Alcohol Studies, Rutgers University Keyword(s): Addiction; Alcohol Use; Gender Differences; Hispanics; Marital Status; Modeling; Modeling, Growth Curve/Latent Trajectory Analysis; Racial Differences; Substance Use Permission to reprint the abstract has not been received from the publisher. Data drawn from the National Longitudinal Survey of Youth on 3,071 Ss age 21+ (38% female, 18% black, 13% Hispanic, ∧ 69% Caucasian) were used to estimate models for heavy alcohol use and bar patronage, 1982-1984. Random effects latent growth models indicate that both heavy alcohol use and bar patronage had downward growth trajectories over time, with males reporting higher levels of both at initial interview and smaller decreases over time. Bar patronage tended to encourage heavy alcohol use, particularly among singles & males. Compared to Caucasians, Hispanics reported lower levels of bar patronage & blacks reported lower levels of both heavy alcohol use & bar patronage. 2 Tables, 4 Figures, 34 References.

The Influence of Changes in Marital Status on Developmental Trajectories of Alcohol Use In Young Adults Journal of Studies on Alcohol 59,6 (November 1998): 647-658. Also: http://www.jsad.com/jsad/article/The_Influence_of_Changes_in_Marital_Status_on_Developmental_Trajectories_of/561.html Cohort(s): NLSY79 Publisher: Center of Alcohol Studies, Rutgers University Keyword(s): Alcohol Use; Education; Ethnic Differences; Gender Differences; Marital Disruption; Modeling, Growth Curve/Latent Trajectory Analysis; Racial Differences; Variables, Independent - Covariate; Youth Problems Permission to reprint the abstract has not been received from the publisher. OBJECTIVE: Multiple group latent curve analysis was used to assess the impact of changes in marital status on alcohol use trajectories in young adults and to test if these effects varied across ethnicity and gender. METHOD: Four years of data were obtained from a sample of young adults (N = 4,052; 54% male) drawn from the National Longitudinal Survey of Youth. Alcohol use and marital status were assessed once per year and covariates included age, gender, education and ethnicity. RESULTS: Latent curve models indicated that there was an overall nonlinear negative alcohol use trajectory across the four time points and that becoming married was reliably associated with an added down-turn to this trajectory. Multiple group models indicated that there was an interaction between ethnicity and marital status in the prediction of alcohol growth trajectories, but there was no interaction with gender. CONCLUSIONS: Becoming married for the first time exerted a unique effect on the overall developmental trajectory of alcohol use over time. This effect held for both ethnic groups but was reliably stronger for white compared to black respondents. This interaction may be attributable to lower levels of alcohol use reported by black respondents, or may be related to individual differences in reactivity to social influences by blacks relative to whites. |

Adolescent and Young Adult Antisocial Behavior and Adult Alcohol Use Disorders: A Fourteen-Year Prospective Follow-Up in a National Survey Journal of Studies on Alcohol 61,4 (July 2000): 524-528. Also: http://www.jsad.com/jsad/article/Adolescent_and_Young_Adult_Antisocial_Behavior_and_Adult_Alcohol_Use_Disord/783.html Cohort(s): NLSY79 Publisher: Center of Alcohol Studies, Rutgers University Keyword(s): Alcohol Use; Behavior, Antisocial; Behavioral Problems; Delinquency/Gang Activity; Modeling; Teenagers; Variables, Independent - Covariate Permission to reprint the abstract has not been received from the publisher. Author: Objective: Data from the National Longitudinal Survey of Youth (NLSY) are used to examine the association between antisocial behaviors (ASB) reported in youth (15-22 years old) and alcohol use disorders (AUD) 14 years later in a large (N = 7,326) representative national sample. Method: Structural equation modeling generalized to dichotomous outcomes was used to assess the associations between latent variables of ASB with latent variables of AUD and background variables. Results: Exploratory factor analysis of 17 ASB items yielded three factors having clear interpretations with the literature-property offenses, person offenses and illicit substance involvement. When examined in the context of the multivariate structural equation model, several independent associations between ASB and AUD symptoms and covariates were found. Although there were significant and independent effects for each ASB factor on each of the alcohol use disorder factors, the strength of the association was strongest for the effects of early illicit substance involvement on alcohol abuse and dependence. Conclusions: Both illicit substance involvement and delinquency other than illicit substance involvement reported in 1980 were associated with alcohol use disorders 14 years later. (J. Stud. Alcohol 61: 524-528, 2000) |

Alcohol Use Among College Students: The Effects of Prior Problem Behaviors and Change of Residence Journal of Studies on Alcohol 62,3 (May 2001): 306-312. Also: http://www.jsad.com/jsad/article/Alcohol_Use_among_College_Students_The_Effects_of_Prior_Problem_Behaviors_/1387.html Cohort(s): NLSY79 Publisher: Center of Alcohol Studies, Rutgers University Keyword(s): Alcohol Use; Behavioral Problems; Educational Status; High School; Residence; Substance Use; Variables, Independent - Covariate; Youth Problems Permission to reprint the abstract has not been received from the publisher. Objective: This article examines the relationship between prior problem behaviors and change in residence on alcohol use patterns among college students. Method: Measures of alcohol consumption (e.g., drinking frequency, average consumption and frequency of heavy episodic drinking) were related to residence patterns and prior problem behaviors (e.g., conduct problems, illicit substance involvement and early age at onset of alcohol consumption). Subjects (N = 2,465; 51% women) were a subsample drawn from the National Longitudinal Study of Labor Market Experience in Youth. The analysis was conducted using a linear growth model for continuous outcomes with time-invariant and time-varying covariates for each of the drinking measures. Results: The results of the structural equation analysis yielded significant and direct effects related to residence patterns and prior problem behaviors. Problem behaviors were related to drinking measures; however, there was no evidence for a mediational hypothesis. Neither was there systematic evidence that the relationship between prior problem behavior and alcohol use was mediated by residence patterns. The analysis of change in residence was related to both time-specific and longer-term influences on alcohol use. Conclusions: The presence of direct and independent effects for both dispositional and high-risk environmental factors in collegiate drinking practices support targeted and diverse strategies for prevention activities.

The Dimensionality of Alcohol Abuse and Dependence: A Multivariate Analysis of DSM-IV Symptom Items in the National Longitudinal Survey of Youth Journal of Studies on Alcohol 62,2 (March 2001): 150-157. Also: http://www.jsad.com/jsad/article/The_Dimensionality_of_Alcohol_Abuse_and_Dependence_A_Multivariate_Analysis/1403.html Cohort(s): NLSY79 Publisher: Center of Alcohol Studies, Rutgers University Keyword(s): Alcohol Use; Diagnostic and Statistical Manual of Mental Disorders; Educational Status; Family History; Health, Mental/Psychological; Health/Health Status/SF-12 Scale; Modeling, Multilevel; Variables, Independent - Covariate Permission to reprint the abstract has not been received from the publisher. OBJECTIVE: This article examines the factor structure of 22 symptom items used to configure the criteria of DSM-IV (Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition) alcohol abuse and dependence and relates the factor structure to background characteristics. METHOD: Data for this study were drawn from the National Longitudinal Study of Labor Market Experience in Youth (NLSY). The symptom items were related to the covariates using the statistical technique of structural equation modeling generalized to dichotomous outcomes. The present model is a special case of structural equation modeling, a multiple causes and multiple indicators (MIMIC) model, in which one or more latent variables (i.e., alcohol abuse and dependence) intervene between a set of observed background variables predicting a set of observed response variables (i.e., DSM-IV symptom items). RESULTS: The results of the structural equation analysis provide further support for two dimensions underlying the DSM-IV symptom items. Although the two-factor dimension bore a strong resemblance to the DSM-IV conceptions of abuse and dependence, there were notable differences in the item content of the symptom items for each dimension. The dependence dimension drew upon items related to the abuse criteria for continued drinking despite social problems and recurrent drinking resulting in failure to fulfill role obligations. The abuse dimension drew upon items related to the abuse criterion for hazardous drinking and the dependence criterion for larger amounts over time. The two factors were shown to have different relationships to the background variables. Alcohol dependence was related to family history of alcoholism and educational status. Age was not related to dependence and inversely related to alcohol abuse. CONCLUSIONS: Findings from this study replicate the two-dimensional model for DSM-IV criteria found in other studies and provide further support for the validity of alcohol dependence i n general population samples. A major implication of the factor structure in the present study relates to the different classification of cases that would otherwise be obtained with DSM-IV criteria. These departures were shown to affect abuse, which retained only 40% of DSM-IV diagnoses, more strongly than dependence, which retained 91% of DSM-IV diagnoses. |

Growth Mixture Modeling with Non-normal Distributions Statistics in Medicine 34,6 (March 2015): 1041-1058. Also: http://onlinelibrary.wiley.com/doi/10.1002/sim.6388/abstract Cohort(s): NLSY97 Publisher: Wiley Online Keyword(s): Modeling, MIxture Models/Finite Mixture Models; Socioeconomic Background; Statistical Analysis Permission to reprint the abstract has not been received from the publisher. A limiting feature of previous work on growth mixture modeling is the assumption of normally distributed variables within each latent class. With strongly non-normal outcomes, this means that several latent classes are required to capture the observed variable distributions. Being able to relax the assumption of within-class normality has the advantage that a non-normal observed distribution does not necessitate using more than one class to fit the distribution. It is valuable to add parameters representing the skewness and the thickness of the tails. A new growth mixture model of this kind is proposed drawing on recent work in a series of papers using the skew-t distribution. The new method is illustrated using the longitudinal development of body mass index in two data sets. The first data set is from the National Longitudinal Survey of Youth covering ages 12-23 years. Here, the development is related to an antecedent measuring socioeconomic background. The second data set is from the Framingham Heart Study covering ages 25-65 years. Here, the development is related to the concurrent event of treatment for hypertension using a joint growth mixture-survival model. |

Integrating Person-Centered and Variable-Centered Analyses: Growth Mixture Modeling With Latent Trajectory Classes Alcoholism: Clinical and Experimental Research 24,6 (June 2000): 882-891. Also: https://onlinelibrary.wiley.com/doi/10.1111/j.1530-0277.2000.tb02070.x Cohort(s): NLSY79 Publisher: Research Society on Alcoholism and the International Society for Biomedical Research on Alcoholism Keyword(s): Alcohol Use; Behavior, Antisocial; Modeling, Latent Class Analysis/Latent Transition Analysis; Modeling, MIxture Models/Finite Mixture Models Permission to reprint the abstract has not been received from the publisher. Background: Many alcohol research questions require methods that take a person-centered approach because the interest is in finding heterogeneous groups of individuals, such as those who are susceptible to alcohol dependence and those who are not. A person-centered focus also is useful with longitudinal data to represent heterogeneity in developmental trajectories. In alcohol, drug, and mental health research the recognition of heterogeneity has led to theories of multiple developmental pathways. Methods: This paper gives a brief overview of new methods that integrate variable- and person-centered analyses. Methods discussed include latent class analysis, latent transition analysis, latent class growth analysis, growth mixture modeling, and general growth mixture modeling. These methods are presented in a general latent variable modeling framework that expands traditional latent variable modeling by including not only continuous latent variables but also categorical latent variables. Results: Four examples that use the National Longitudinal Survey of Youth (NLSY) data are presented to illustrate latent class analysis, latent class growth analysis, growth mixture modeling, and general growth mixture modeling. Latent class analysis of antisocial behavior found four classes. Four heavy drinking trajectory classes were found. The relationship between the latent classes and background variables and consequences was studied. |

The Development of Heavy Drinking and Alcohol-Related Problems from Ages 18 to 37 in a U. S. National Sample Journal of Studies on Alcohol 61,2 (March 2000): 290-300. Also: http://www.jsad.com/jsad/article/Early_Alcohol_Use_Rural_Residence_and_Adult_Employment/2226.html Cohort(s): NLSY79 Publisher: Center of Alcohol Studies, Rutgers University Keyword(s): Addiction; Alcohol Use; College Education; Educational Attainment; Ethnic Differences; Ethnic Groups/Ethnicity; Family Background and Culture; Family History; Gender; High School Dropouts; Racial Differences; Substance Use Permission to reprint the abstract has not been received from the publisher. Investigated the influence of individual background variables on the development of heavy drinking and alcohol-related problems by examining data from the National Longitudinal Survey of Youth, a general population sample (7,859 Ss) that contains information on alcohol use for the ages 18-37 yrs. Background variables included gender, ethnicity, family history of problem drinking, early onset of drinking, high school dropout, and college education. The study used a multivariate outcome approach that focused on individual variation in trajectories over age. The statistical analysis used random coefficients in a latent variable framework. Across-age changes in the importance of the influence of background variables on the outcomes were modeled using varying center points. A key finding is that dropping out of high school has no effect on alcohol-related problems for individuals in their mid-20s, but is associated with significantly increased levels of alcohol-related problems for individuals in their mid-30s. In contrast, going on to college is associated with lower levels of heavy drinking when individuals reach their late twenties and their thirties. Strong gender and ethnicity effects seen in the twenties diminish when individuals reach their thirties. ((c) 2000 APA/PsycINFO, all rights reserved) |
